Final answer:
The maximum effective range of the M16A2 on a point target is approximately 550 meters. A larger muzzle velocity would increase the range, but air resistance can decrease its effectiveness.
Step-by-step explanation:
The maximum effective range of the M16A2 on a point target is approximately 550 meters. This means that the rifle is most accurate and effective when aimed at a target up to 550 meters away.
The muzzle velocity of the M16A2 is around 975 meters per second. A larger muzzle velocity would increase the range of the rifle, allowing it to accurately hit targets at farther distances.
Air resistance can affect the trajectory of the bullet and decrease the effective range of the rifle. It can cause the bullet to lose velocity and drop more quickly, reducing its accuracy at longer distances.
